Description

Technical Field

[0001] This utility model belongs to the technical field of surveying and positioning equipment, and specifically relates to an RTK and prism integrated measurement device. Background Technology

[0002] During the construction period of hydropower stations and pumped storage power stations, the work sites are often located in high mountains and valleys or areas with complex geological conditions. Frequent surveys of steep slopes, deep foundation pits, and the topography of the excavation face are required to accurately calculate the amount of earthwork excavation and backfilling. Since RTK surveying requires handheld operation, it is often difficult to reach these dangerous and complex terrains such as steep slopes or deep foundation pits safely. Therefore, it is often necessary to combine it with a total station for remote surveying operations.

[0003] At this point, it is usually necessary to first establish control points using an RTK (Real-Time Kinematic) instrument, and then set up a prism and a total station at the control points for measurement. However, when establishing control points with an RTK, it is necessary to manually hold the pole continuously to keep the circular level bubble centered, which is prone to human error. After the control points are measured, the RTK must be removed before setting up the prism to perform total station measurements, which increases the number of steps and time costs. Utility Model Content

[0004] This invention provides an integrated RTK and prism measurement device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An integrated RTK and prism measuring device includes an RTK measuring device, which includes a support rod and an RTK receiver. A universal connector is installed on the top of the RTK receiver, and a prism for cooperating with a total station is installed on the universal connector.

[0007] An auxiliary support frame is also sleeved on the outside of the support rod. The height of the auxiliary support frame is adjustable to maintain the stability of the RTK measuring device.

[0008] Furthermore, a height adjustment bolt is provided on the support rod near the RTK receiver, and a circular bubble level is fixed on the height adjustment bolt.

[0009] Furthermore, the auxiliary support frame includes a main bipod and a secondary bipod, with the main bipod positioned above the secondary bipod, and the mounting plane of the secondary bipod intersecting with the mounting plane of the main bipod.

[0010] Furthermore, each support leg of the main tripod and the secondary tripod is equipped with a threaded leveling handle, which is located near the top of the RTK measuring device.

[0011] Furthermore, a circular bubble level is also installed above the secondary tripod.

[0012] Furthermore, the auxiliary support frame includes a mounting disc, and the mounting disc has multiple mounting holes circumferentially.

[0013] Each of the mounting holes is rotatably provided with a hinge ball, and a threaded hole is opened through the hinge ball. A support leg can be threadedly inserted into the hinge ball, and at least two support legs are provided.

[0014] Furthermore, the articulated ball is also provided with a first mating groove that communicates with the threaded hole, and the first mating groove penetrates the side wall of the articulated ball;

[0015] The mounting disc is also provided with a second docking groove, which is connected to the mounting hole, and the hinge ball can rotate until the first docking groove and the second docking groove are aligned.

[0016] Furthermore, the support leg includes multiple unit segments arranged sequentially along the length direction, each unit segment including a smooth segment and a threaded segment, wherein the maximum outer diameter of the threaded segment is greater than the outer diameter of the smooth segment;

[0017] The diameter of the smooth section, the width of the first mating groove, and the width of the second mating groove are all the same, and the threaded section is used for threaded connection with the threaded hole.

[0018] Furthermore, the top of the RTK receiver is integrally formed with a forced alignment screw hole, and the universal connector can be detachably installed in the forced alignment screw hole.

[0019] Furthermore, the vertical height difference between the optical center of the prism and the phase center of the RTK receiver antenna is a fixed value ΔH, and the design tolerance of ΔH is within ±1mm.

[0020] The central axis of the forced alignment screw hole is coaxial with the phase center of the RTK receiver antenna, and the coaxiality error is no greater than ±0.5mm.

[0021] The present invention can achieve the following beneficial effects:

[0022] 1. This application enables the total station to directly aim at the prism and set up the station as soon as the RTK measuring device completes the control point measurement. This eliminates multiple steps such as removing the RTK from the control point, setting up the prism frame, and re-leveling and aligning, which greatly improves measurement efficiency, shortens measurement time, and only requires one installation and leveling, thus reducing measurement errors.

[0023] 2. Setting up an auxiliary support frame can improve the installation stability of the RTK measurement device and eliminate the shaking error caused by manual support; in addition, in one embodiment, the RTK receiver uses a main tripod and a secondary tripod for easy and quick installation, and leveling is also more convenient.

[0024] 3. In another embodiment, a mounting disk is installed on the support rod, and multiple support legs are detachably installed on the mounting disk to achieve stable placement of the RTK measurement device, which can reduce the difficulty of moving the instrument and make the setup quick and convenient.

[0033] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0034] Example 1

[0035] like Figure 1 and Figure 2 As shown, an integrated RTK and prism measuring device includes an RTK measuring device 1 and an auxiliary support frame 3. The RTK measuring device 1 includes a support rod 11 and an RTK receiver 12. The RTK measuring device 1 is an existing finished device, and its structure and function will not be described in detail here. The top of the RTK receiver 12 is integrally formed with a forced centering screw hole. A universal connector is detachably installed in the forced centering screw hole, and a prism 2 for use with a total station 100 is installed on the universal connector. The universal connector and the forced centering screw hole are precision threaded, and the connection is stable through an anti-loosening locking ring to ensure that the positioning accuracy is maintained after multiple disassemblies and reassemblies.

[0036] To ensure measurement accuracy, the vertical height difference between the optical center of prism 2 and the phase center of the RTK receiver 12 antenna is set to a fixed value ΔH. The design tolerance of ΔH is controlled within ±1mm. Furthermore, the central axis of the forced alignment screw hole is strictly coaxial with the phase center of the RTK receiver 12 antenna, with a coaxiality error of no more than ±0.5mm, ensuring the rigidity of the integrated structure and the accuracy of the measurement.

[0037] A height adjustment bolt 13 is provided in the area of ​​the support rod 11 near the RTK receiver 12. A circular bubble level 4 is fixed on the height adjustment bolt 13. The height of the RTK measuring device 1 can be adjusted by rotating the height adjustment bolt 13, and the position of the bubble in the circular bubble level 4 can be observed at the same time to achieve the initial horizontal calibration of the RTK measuring device 1.

[0038] The auxiliary support frame 3 is used to maintain the stability of the RTK measuring device 1 and its height can be adjusted according to terrain requirements. This application discloses two embodiments of the auxiliary support frame 3:

[0039] Example 1:

[0040] Reference Figure 1 and Figure 2 The auxiliary support frame 3 includes a main tripod 31 and a secondary tripod 32. The main tripod 31 is positioned above the secondary tripod 32, and the mounting plane of the secondary tripod 32 intersects with the mounting plane of the main tripod 31, forming a cross-support structure to improve the overall stability of the RTK measuring device 1. It should be noted that... Figure 2 The main tripod 31 is not shown. Each leg of both the main tripod 31 and the secondary tripod 32 is equipped with a threaded leveling handle 311. Each leg consists of two sections connected by the threaded leveling handle 311. The length of each leg is adjusted by rotating the threaded leveling handle 311 in both directions. The threaded leveling handle 311 is positioned near the top of the RTK measuring device 1 for easy and rapid application of force by the operator during leveling.

[0041] A circular bubble level 4 is also installed above the secondary tripod 32 to cooperate with the circular bubble level 4 on the support rod 11 for double level calibration. During installation, the main tripod 31 is first fastened and fitted onto the support rod 11. After adjusting the main tripod 31 to a suitable height, the secondary tripod 32 is then fitted onto the support rod 11 below the main tripod 31, and its height is adjusted and fixed. Subsequently, the operator rotates the threaded leveling handles 311 of the main tripod 31 and the secondary tripod 32 respectively, while observing the corresponding circular bubble level 4, until the bubbles of both bubble level 4 are in the centered position, completing the stable setup of the RTK measuring device 1. At this point, no manual continuous support is required, effectively eliminating the shaking error caused by the support. This embodiment is suitable for measurements on relatively flat terrain because the length adjustment range of the auxiliary support frame 3 is small.

[0042] Example 2:

[0043] Reference Figure 3 and Figure 4 In the second embodiment, the auxiliary support frame 3 includes a mounting disc 33 and at least two support legs 5. The mounting disc 33 is fixedly sleeved on the support rod 11, and the support legs 5 are detachably mounted on the mounting disc 33. Specifically, the support legs 5 include multiple unit segments arranged sequentially along the length direction. Each unit segment includes a smooth segment 51 and a threaded segment 52, and the maximum outer diameter of the threaded segment 52 is greater than the outer diameter of the smooth segment 51.

[0044] The mounting disk 33 has multiple mounting holes 331 circumferentially. The diameter of each section of the mounting hole 331 is different along the thickness direction of the mounting disk 33, and the inner wall of the mounting hole 331 is arc-shaped. A hinge ball 34 is rotatably disposed in each mounting hole 331. The hinge ball 34 protrudes from the surface of the mounting disk 33, thereby ensuring that the hinge ball 34 is confined within the mounting hole 331, but can rotate within the mounting hole 331.

[0045] A threaded hole 341 is formed through the hinge ball 34, and the threaded hole 341 matches the threaded section 52 to achieve a threaded connection between the hinge ball 34 and the support leg 5. The hinge ball 34 also has a first mating groove 342 communicating with the threaded hole 341, and the first mating groove 342 penetrates the side wall of the hinge ball 34. Simultaneously, a second mating groove 332 communicating with the mounting hole 331 is formed on the mounting disc 33, and the second mating groove 332 penetrates the side wall of the mounting disc 33. The widths of the first and second mating grooves 342 and the diameter of the smooth section 51 are all the same. It should be noted that... Figure 4 The image shows the state after the articulated ball 34 rotates to align with the first mating groove 342 and the second mating groove 332, as well as the state after they are misaligned. Additionally... Figure 4 The location of the mounting holes 331 is only for illustration; the arrangement density of the mounting holes 331 can be selected as needed.

[0046] When assembling the support leg 5, select a suitable unit segment and align it with the second docking groove 332 according to the height and flatness of the working terrain, and move the smooth section 51 of the corresponding unit segment into the threaded hole 341. At this time, rotate the support leg 5 so that the threaded section 52 is screwed into the threaded hole 341 of the hinge ball 34. By rotating the support leg 5, the length of the support leg 5 can be adjusted within a small range. By rotating the hinge ball 34, the contact angle between the support leg 5 and the ground can be adjusted. At the same time, observe the circular bubble level 4 on the support rod 11 until the bubble is centered, and the stable placement of the device is completed. This design not only reduces the difficulty of transporting the instrument, but also makes the setup process quick and convenient, and is suitable for a variety of complex terrains, especially for terrains with large slopes, where it can be installed relatively easily and quickly.

[0047] In actual measurement operations, regardless of the type of auxiliary support frame 3 used, after the installation and leveling of the integrated RTK and prism 2 measuring device 1 are completed, the control points of the map are first measured through the RTK receiver 12. For example, the device is set up at control point A, and the RTK receiver 12 is operated to trigger the measurement function. Multiple measurements can be taken and the average value is calculated as the final coordinates of point A to ensure the accuracy of the coordinates of control point A. After the measurement is completed, there is no need to remove the RTK measuring device 1. The total station 100 is directly set up at a known reference point, such as control point B, which has been measured using the RTK measuring device 1. The coordinates of control point A and control point B are input into the total station 100, and control point B is used as the measurement station. At this point, the height of the support rod 11 fixed by the height adjustment bolt 13 is read, and this height is added to the fixed height difference ΔH to obtain the actual height of the prism 2. This height is then input into the total station 100 as the height of the prism 2. Finally, the universal connector is gently rotated to adjust the direction of the reflecting surface of the prism 2 so that the reflecting surface is precisely aligned with the line of sight of the total station 100. The total station 100 can then directly aim at the prism 2 to measure the distance, quickly completing the station setup operation and proceeding with subsequent topographic surveying. The entire process eliminates multiple steps such as removing the RTK measuring device 1 from control point A, setting up the prism 2, and re-leveling and aligning, greatly improving measurement efficiency. At the same time, only one installation and leveling is required, effectively reducing measurement errors caused by multiple operations.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
